[wix-users] Unable to correctly specify a variable for WiX within Visual Studio

[Jon Earle]

Thank you for responding to my inquiry.
1. How do I create the <JavaDocBase> property from the project properties page? All I see when I shell out to the commandline and view the wixproj file is the <DefineConstants> property.  Trying to do all this via the gui as much as possible because there will be others who will eventually maintain this and I want to make it as simple as possible.
2. Where does the <Bundle> property enter the picture?  It's not mentioned in any of my files...
3. HeatDirectoryTask... why did I not use it?  Many reasons: a) did not know about it b) don't know how to use it (including, where to put it) c) I am reading a lot of what appears to be conflicting or incorrect or incomplete information on the 'Net and trying to gain a working understanding out of it all.  
Cheers!Jon

I had read (http://weblogs.sqlteam.com/mladenp/archive/2010/02/11/WiX-3-Tutorial-SolutionProject-structure-and-Dev-resources.aspx) to set a pre-processor variable (or system variable). I opted to include the variable definition in the project. I tried the pre-processor var <DefineConstants>JavaDocBase=c:\javadocs</DefineConstants>
> and just setting a normal variable:
> <WixVariables>JavaDocBase=c:\javadocs</WixVariables>
> Neither ended up working.

> I have tried var.JavaDocBase, wix.JavaDocBase, env.JavaDocBase and Just JavaDocBase... while the last will allow the command to run, it doesn't put in the proper path so I am no further ahead.
